JLPT: youngest person to pass N1?

Question:

I know this is hard to answer but I was curious. How old is the youngest person you know, or have heard of, who passed N1?

The material is very advanced, not only in the breadth of vocabulary and kanji, but also in content. It seems unlikely that someone would be able to pass it at say 10 or 12 years old because they just wouldn't understand the content. However, I have heard that it is sometimes a criteria for admission into high school in Japan for 帰国子女. (Though that might actually be 日本語検定)

Anyway, let me know if you know anyone who was young and passed the test.

Answer:

This N1-N5 level system started just in 2010. There were 4 levels before that. If you do not include the old levels, it's too early to talk about its "history".
